RIER.

Application filed July 1, 1921. Serial No. 481,794.

To aZZ whom it may concern a Be it known'that I, ELwooD'B. AYREs, a citizen of the United States, residing in Philadelphia, Pennsylvania, have" invented certain Improvements inDrier's, of which the following is a specification.

=My invention relates to certain i1nprove ments in 'driers, partlc ularly ior dry1ng p0r-.

celain ware. i v

The object of my invention is to design a drier so that the Ware is first subjected to air in circulation having a high humidity,

thensubjectedlto'fairin circulation having high temperature and loW'humidity, and is finally cooled by air passing through an independent channel in the drier.

In the accompanying drawings Fig. 1 is a longitudinal sectionalview, o

" .my improved drier,

Fig. 2 isa transverse sectional view on the line.2'2, Fig. 1; and- I i y Fig. 3 is a sectional plan vieW"on the line 3-3, Fig. 1', of one side of the drier.

1 isthe casing of'the driershown in outline, but it Will bejunderstood that it may be A made inany suitable manner In the casing fig) is an inner, transverse partition formed by two vertical Walls 2 and;3 and a horizontal section 4. "The walls 2 and 3 are spaceda given-distance from the front and rear ends of the outer casing, and-the horizontal section 4 is likewise spaced from the bottom, as

shown in Fig. 1, to fOrmpaSSagesa, b c. 5 is v a central vertical partition stopping short of the section 4 and dividing the central por tion of the drying chamber into compartments (5 and 0-.

6 is an endless conveyor having carrying trays 7 for the porcelain, orothe'r ware. The trays are so arranged that they remain horizontal in passing through the drier. 8 are the upper guide wheels for-the conveyer and 9 are the lower uidewheels 10 are the lower guide whee s for the outer run of the conveyer. The conveyer travels in vertical paths in the direction of the arrows.

11 isthe feed opening of'the drier and 12 isthe delivery opening. 13 and 14 are circulating fans and in the independent heating chambers 21 and 22, respectively, at the side ofthe drier,- are the heating '15. The vertical partition 16 separates the ,a'nd is discontinued at 17 and;

to the'heating chamber from the'drying chamber. f

being cooledand ready to recelve load at thefeed' pipes 15,. heating chamber frolnthe drying chamber 18 forming passages for the air to return At the delivery end ofthe drier is an ex- 4 haust fan 19 connected by a duct 20 with the upper portion of the rear passage. The air in the compartment 6 is kept 'at about 120 degrees; and at a high humidity, while the air in the compartment-e is kept at'about 17 5 degrees and at a low humidity so;that the ware, as t enters the compartment cl from the passage a, is subjected to theair at low temperature and a high humidity, preventa ing the too-rapid drying and cracking of the Ware. The ware isthen conveyed into and through the compartment e, where it is subjected to a comparatively high temperatureand low ,liumidity, From this compartment,

it is conveyed through'the passage ,6 to the delivery opening 12, Air at about lOOdegrees enters the passage through this opening 12 and isexhausted through thefan 19.

jThismovement of the air cools the ware to about IOOdegrees. Theconveyer then travels through the lowe'r passage 0, the trays another opening 11. I claim: 1. The; combination in a drier, of a casing; an ]inner transverse partition spaced from the ends and bottom of the casing forming a drying chamber and passages; a '85 transverse partition dividing the chamber nto two compartments independent means for heating the air in'ea'ch compartment; in-

dependent means for circulating the air in the compatments in order that the air in. 90. one compaitment may be regulated so as'to be high in humidity and of low temperature,

theair inthe other compartment having'a higher temperature and a lower humidity; and means for conveying material through '95 the said compartments and passages.

2. The combination in a drier, of a casing; a drying chamber therein having two compartments; an independent heating chamber connected to each compartment; a

circulating fan for independently circulat- -ing the air in each cor'npaitmentv so that the air in the first compartment may be regulated so as to be high in humidity and low in temperature while the air in the secondcomartmnt may be-regulated so as to be 10W 1n humidity and of higher temperature; a

the rearpassage.

rear passage in the casing; an exhaust fan communicating with said passage so as to create a current ofcold air therein; and a. tray conveyer passing in Vertical paths through the two compartments and through ELWOOD BL AYREs.
